Miner to mine

1.

mining chip has gone from CPU mining to GPU mining to FPGA mining, and now it has entered the era of ASIC mining. However, the way of mining has also experienced from one or two mining machines to small mining machine workshops, and now it has entered the era of large-scale mining

(1) mining mode: from one miner to large-scale mine

if you start to try mining, you need to prepare a miner, a computer with internet connection, an AUC, a raspberry pie, power supply and various connecting cables. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

Bitmine is real

bitcoin is proced by mining. Every 10 minutes, the miners of the whole network work out an arithmetic problem together. Whoever works out the answer first is equivalent to digging into this block, and the miner can get the bitcoin reward of system rebirth

after bitcoin is g in the mine, the income is distributed according to the proportion of the mine's computing power, so as to ensure a more stable input-output

every other time point, bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

5. Hello, the miner trusteeship depends on the situation
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time
if there are dozens or even hundreds of mine machines, it is recommended that you choose mine trusteeship. First, the electricity charge of mine trusteeship will be cheaper than that of indivials, and there are special personnel to take care of mine machines. The inconvenience may be that most of the mines are located in Northwest and southwest provinces, which may not be convenient for you to understand the actual situation, but you can also choose the background software to monitor your own mine machines, The selection of specific mines can be evaluated according to the quotation
if you don't know much about this area before and don't have a miner, you can choose to buy cloud computing power. This kind of miner is only used in a different way. The ownership of the miner doesn't belong to you, but is rented to you

the advantage of the mineral machinery trusteeship lies in the fact that it is not easy to manage; Annual regular electricity subsidies, cheap electricity; 24 hours a day without power cut to dig money; There is operation and maintenance technology in the mine 24 hours on call, problems can be solved immediately; If the power board is broken, it needs to be returned to the factory. The company will have machines to make up the power. However, it is suggested that when you choose a mine, you should consider the quotation of mine management fee and electricity fee
if you have any other questions, please ask me. I hope I can help you, thank you!

6. If there is no direct subway to Longgang central city, you need to transfer. Take subway line 1 (Luobao line) at the railway station, Luohu station, take 2 stops to Laojie station, and then transfer to Metro Line 3 (Longgang line) to Jixiang station or Longcheng square, and then transfer (take 358 and 833 at Jixiang station, 329 and 365 at Longcheng square, and you can get to Tianhong, the central city, etc.)

8. They have their own mines, of course, but they need to buy more mining machines to expand their scale by selling their computing power. Generally speaking, the larger the scale of cloud computing power platform, the more stable the computing power and the more considerable the benefits. It is a win-win situation for both investors and platforms to buy computing power on large platforms such as micro travel cloud.

9. In fact, a large number of mining machines are assembled in a mine. After all, the computing power of a mining machine is limited, and now the computing power of the whole network is also very large. If you combine many mining machines together, the computing power will be greater and it will be easier to dig the mine.
